Using City Concatenation Functions in Snowflake for Efficient Data Analysis
Understanding the Problem and Requirements We’re given a table with three columns: employee, city, and color. The goal is to find every city mapped to an employee (from any row) and display them concatenated for every row where this employee is present. In other words, we want to group all cities associated with each employee across different rows and concatenate them into a single string.
